﴿ فَكَيْفَ كَانَ عَذَابِى وَنُذُرِ ﴾

“for, how severe is the suffering which I inflict when My warnings are disregarded!”

Then see how (dreadful) was My punishment after My warnings!) See, O Muhammad, how was My punishment of them, and how was the state of those who were warned by Hud but did not believe him.
